Given that:
Pass percentage of school S = pass percentage of school Q
Students passed in S = 50, students passed in Q = 90

Formula Used:
Percentage = (Actual/Total) × 100

Calculation:
Let the pass percentage of students = x %
So, the total strength of school S = (50/x) × 100 = 5000/x
Total strength of school Q = (90/x) × 100 = 9000/x
The total strength of school Q is more than that of school S = (9000/x) – (5000/x) = 4000/x
The required % = [(4000/x)/(5000/x)] × 100 = (4/5) × 100 = 80%
∴ Total strength of school Q is 80% more than that of school S

Given Details

Twelve friends—Jishnu, Jay, Hari, Balu, Abhi, Keshav, Ambani, Sanju, Daya, Sreerag, Rohan, and Raghu.
Four different villas; Villa A, Villa B, Villa C, Villa D
Each villa has at least two people and at most four people staying.
Villa C has the least number of people staying in it.
Villa B and Villa D have three people staying in each villa.
Here we get Villa C has two people Staying (Two is the least) and Villa B and Villa D have three people staying in each Villa. So the remaining four people will stay in Villa A.

Keshav and Ambani stay together.
Keshav stays in the villa with the least number of people.
Here we get Keshav and Ambani staying together in Villa C

Balu is staying in Villa A. Sanju stays with three other people. Jay stays in a Villa having even number of people. Here Sanju stays with three other people so he stays in Villa A and Jay stays in Villa A, which has an even number of people staying in it.

Sreerag and Abhi stay in the same Villa but not in Villa D. Jishnu stays with 2 other people. Here we get Sreerag and Abhi staying in Villa B. For Jishnu there are 2 cases

Case 1: Jishnu stays in Villa B.

Case 2: Jishnu stays in Villa D.

Rohan and Raghu stay together but not in the Villa B.
Neither Daya nor Hari does not stays in Villa B.
Daya stays with 2 other people only.
Here we get the final case as Hari stays in Villa A and Daya in Villa D

Hence, Rohan stays in Villa D.

The correct answer is i.e. 'C' this part of the sentence has an error.

Key Points

• In the third part of the sentence 'about' should be omitted.
• This is an example of superfluous sentence.
• Discuss is not followed by any preposition.

Hence the correct answer is option 3.

Additional Information

• There are certain verbs which are not followed by any preposition e.g. consider, influence, emphasize etc.

The correct answer is "has an indigenous."

Key Points

• The subject in the given sentence is "India" which is a singular noun.
• "Have" is used with some pronouns and plural nouns while "has" is used with the third person singular or singular nouns.
  • Thus, it can be inferred that option 1 will be eliminated.
• Now, let us understand the meaning of the following:
  • "Indigenous" is (used about people, animals, or plants) living or growing in the place where they are from originally.
    • Example: The park is also home to indigenous tribes.
  • "Ingredient" means one of the qualities necessary to make something successful.
    • Example: Friendship is an essential ingredient in the making of a healthful, rewarding life.
• In the given sentence, the blank will elaborate more about the Light Combat Helicopter. Thus, the correct word to use will be "indigenous."
  • Thus, options 2 and 4 will be eliminated.
• Also, we know that "an" is used when the noun that follows begins with a vowel sound.

Hence, it can be concluded that the correct answer is option 3.

Given :

50% of the total work by A + B in = 6 days

Efficiency of B = 50% more than A

Efficiency of C = 25% more than A

Calculation :

Time taken by (A + B) to complete the 100% of the work = 6/0.50 = 12 days

Efficiency ratio of A : B : C = 100 : 150 : 125 = 4 : 6 : 5

Total work = (4 + 6) × 12 = 120 units

Time taken by (B + C) to complete the 75% of the work = (120 × 0.75)/(6 + 5) = 90/11 days

Hence, the correct answer is 90/11 days.

Given:

In 4 years a sum became Rs. 1200

In 6 years the sum became Rs. 1500

Formula used:

S.I = PRT/100

Where S.I = Simple interest, P = Principal, R = Rate, T = time

Calculation:

SI for 2 year = 1500 - 1200 = 300

⇒ SI for 4 year = 300 × 2 = 600

So, Principal = 1200 - 600 = 600

Now,

600 = (600 × r × 4)/100

r = 100/4 = 25%

∴ The rate of interest per annum is 25%

The least possible Venn diagram for the given statements is as follows -

Conclusions:

1). Some Investors are not Entrepreneurs. → False (There is no negative relation given between Investors and Entrepreneurs. It is possible that All Investors are Entrepreneurs. So it is not definite that Some Investors are not Entrepreneurs. Hence, it doesn't follow.)

2). Some Startups are not Innovations. → False (There is no negative relation given between Startups and Innovations. It is possible that All Startups are Innovations. So it is not definite that Some Startups are not Innovations. Hence, it doesn't follow.)

3). Some Investors are not Startups. → True (It is given that No Startup is Entrepreneur and Some Entrepreneurs are Investors. So the part of Investors which is Entrepreneurs can never be Startups. Hence, it follows.)

4). Some Entrepreneurs are Innovations. → False (It is given that All Innovations are Startups and No Startup is Entrepreneur. So it is definite that No Entrepreneur is Innovation. Hence, it doesn't follow.)

5). Some Startups are Investors. → False (There is no direct relation given between Startups and Investors. So it is not definite that Some Startups are Investors. Hence, it doesn't follow.)

Hence, the correct answer is Some Investors are not Startups.

Concept:-
Binary Search: Search a sorted array by repeatedly dividing the search interval in half. Begin with an interval covering the whole array. If the value of the search key is less than the item in the middle of the interval, narrow the interval to the lower half. Otherwise, narrow it to the upper half. Repeatedly check until the value is found or the interval is empty.

Binary search algorithm(BSA) applied only when array must be sorted

A is an array of n elements

p is starting index of array A

q is the last index of array A

v is the element that we want to search

BSA (A, p, q, v)

while( q - p 0)

{

mid ←

if(A[mid] == v)

then return m

if(A[mid] > v) // if element present in lower half of the array

then q ← mid - 1

else

p ← mid + 1

}

return 0

Analysis:-

At first level key = 91
At second level key = 99
Here 90 and 99 are mid values.
91+ 99 = 190 would be the answer.

The correct answer is option 4.

Concept:

The script is executable before we run it. After that, run the script by invoking the script name. We must use chmod +x script name to make the script executable. To run the script, we should make it executable first by using chmod +x.

chmod +x filename: We gave the file run permission for all users (user, group, other).

chmod +r filename: We have given read permission to the file.

chmod +w filename: We have given written permission to the file.

chmod +rwx filename: Read, write and run access permissions are all available.

Hence the correct answer is chmod +x.

*args - It is a special syntax in python which is used to pass a variable number of arguments in the function. The number of arguments is not fixed and can have any number of arguments passed.

• The type of arguments passed are non-keyworded arguments.
• It is stored in a tuple when passed to a function.

**kwargs - It is a special syntax in python which is used to pass a variable number of keyworded arguments in the function. The number of arguments is not fixed and can have any number of arguments passed.

• The type of arguments passed are keyworded arguments only and not non-keyworded as it will then throw an error because we are using double asterisks with kwargs.
• It is stored as a dictionary when passed to a function.

The correct answer is ciphertext

• Cipher is an algorithm that is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term "cipher" is sometimes used as an alternative term for ciphertext. The ciphertext is not understandable until it has been converted into plain text using a key.
• Earlier cipher algorithms were performed manually and were entirely different from modern algorithms which are generally executed by a machine. Different types of ciphers exist, some of which are:
  • Substitution Cipher: This offers an alternative to the plaintext. It is also known as Caesar cipher.
  • Polyalphabetic Substitution Cipher: In this cipher, a mixed alphabet is used to encrypt the plaintext, but at random points, it would change to a different mixed alphabet which indicates the change with an uppercase letter in the Ciphertext.
  • Transposition Cipher: This cipher is also known as Rail Fence Cipher and is a permutation of the plaintext.
  • Permutation Cipher: The positions held by plaintext are shifted to a regular system in this cipher so that the ciphertext constitutes a permutation of the plaintext.

Definition of two-dimensional array

float ary[x][9];

Number of rows: x

Number of columns: 9

9x = 117

Circular linked list:
In singly linked lists and doubly linked lists, the end of lists is indicated with a NULL value. But circular linked lists do not have ends. In circular linked lists, each node has a successor, and the last node points to the first node instead of NULL.

Example

Let x be a variable pointer and head.

Head is the pointer of the circular linked list.

Now to insert a new record (node) y, we have to loop through the linked list from the head to the last node like this pseudocode below.

x=head

while(x->next!=head)

{

x=x->next;

}

After finishing the loop x is now the last node and we will append the list. y is the next node of x Then the next of y will have to point to the head since the linked list is circular.

Concept:

For a natural join operation R * S on two relations R and S, only tuples from R that have matching tuples in S and vice versa can appear in the result. Tuples without matching are eliminated from join result. Tuples with NULL values are also eliminated. It results in loss of information.

Explanation:

A set of operations called outer join, can be used when we want to keep all the tuples in R or all those in S or all those in both relations in the result of JOIN., regardless of whether or not they have matching tuples in other relation.

Example: Consider a relation Employee (Employee name, phone no, department) and another relation MANAGE (Department, building no.). Suppose that we want a list of all employee names and also the name of department they manage if they happen to manage a department, if they do not manage one, we can indicate it with a NULL value.

Outer join will result in:
